CLASS INTERNATIONAL SWEDISH A61 f30d: 14 PATENT AND REGISTRATION AGENCY Ans. 3729/1960 filed on 1314 1960 posted on 12/4 196 JOHNSON & JOHNSON, NEW BRUNSWICK, N.J. USA Swellable tampon Inventor: G Brecht roch G G Graham jr Priority requested before 17 April 1959 (USA) The present invention relates to tampons and in particular to a new and improved menstrual tampon, which expands greatly upon wetting and thus provides more effective protection against menstrual fluid.

Vagina har i allmanhet formen av ett platttryckt ror, som begransar ett plan, som är omkring 8-10 cm langt och minskar i bredd fran omkring 5-6 cm vid cervix till praktiskt taget ingenting vid vaginas oppning. Riktningen hos det av det platt-tryckta rOret begransade planet i forhallande till kroppen beror pa kroppens stallning, dvs. riktningen vaxlar i forhallande till kroppen beroende pa om denna intar liggande, staende eller sidolage. The vagina generally has the shape of a flattened tube, which delimits a plane that is about 8-10 cm long and decreases in width from about 5-6 cm at the cervix to practically nothing at the opening of the vagina. The direction of the plane delimited by the flattened tube in relation to the body depends on the position of the body, i.e. the direction changes in relation to the body depending on whether it occupies lying, standing or side position.

Dâ en tampong infores i vagina, for den dess vaggar at sidan, sa att en oppning bildas for tampongen. For underlattande av info-ring och urtagning och for att Ora anvandningen bekvam arc vanliga menstruationstamponger vanligen cylindriska och ha en avsevart mindre storlek an vagina. Av detta skill ha konventionella tamponger, som aro bildade av kraftigt hoppressat, absorberande material till en langstrackt cylinder, en diameter pa omkring 11-16 mm och en langd pa omkring 40-50 mm. Pa grund av skillnaden i storlek mellan en konventionell tampong och vagina uttyller tampongen icke vagina och blir i manga fall belagen vid en sidovagg. Som en fOljd darav kan menstruationsvatska passera forbi tampongen och stromma ut genom vaginaoppningen, sä att tampongen icke fungerar effektivt. When a tampon is inserted into the vagina, for it then rocks to the side, so that an opening is formed for the tampon. For ease of infiltration and removal and for ora use comfortable arc regular menstrual tampons are usually cylindrical and have a considerably smaller size than the vagina. Of this distinction, conventional tampons formed from highly compressed absorbent material into an elongate cylinder have a diameter of about 11-16 mm and a length of about 40-50 mm. Due to the difference in size between a conventional tampon and the vagina, the tampon does not fill the vagina and in many cases is covered by a side cradle. As a result, menstrual fluid can pass the tampon and flow out through the vaginal opening, so that the tampon does not work effectively.

Emedan vagina har formen av ett platttryckt r6r star en konventionell tampong blott i kontakt med vissa delar av vaggarna i vagina och icke med de &riga. I sjalva verket blir resultatet detsamma som da man infor ett foretrial av cylindrisk form i en langstrackt slits. Foremalet kan berora de byre och undre vaggarna i slitsen men vara utan kontakt med sidovaggarna. • Vid anvandningen utvidgas konventionella, kraftigt hoppressade tamponger i flagon man. Vid absorption av menstruationsvatska utlosas en del av de krafter, som halla det absorberande fibermaterialet i fixerat tillstand, sa att tampongen kan expandera mar eller mind-re likformigt och Oka i storlek. Emellertid ãr storleksokningen och dennas riktning pa grund av denna expansion mycket liten och utan betydelse, da det galler att bilda ett mera effektivt skydd mot flodet av menstruationsvatska. Storleksskillnaden mellan vagina och den expanderade tampongen, sarskilt ifraga om tampongens diameter och vaginas bredd är praktiskt taget densamma som fore tampongens svallning. Because the vagina has the shape of a flattened tube, a conventional tampon is only in contact with certain parts of the cradles in the vagina and not with the others. In fact, the result is the same as when inserting a preform of a cylindrical shape into an elongated slot. The form may touch the upper and lower cradles in the slot but be without contact with the side cradles. During use, conventional, heavily compressed tampons in the flagon man are expanded. Upon absorption of menstrual fluid, some of the forces that keep the absorbent fibrous material in a fixed state are released, so that the tampon can expand more or less uniformly and increase in size. However, the increase in size and its direction due to this expansion is very small and insignificant, as it is necessary to form a more effective protection against the flow of menstrual fluid. The size difference between the vagina and the expanded tampon, especially when it comes to the diameter of the tampon and the width of the vagina, is practically the same as the swelling of the front of the tampon.

Foreliggande uppfinning avser en tampong som expanderar avsevd.rt efter inforande i vagina for att ge ett mera effektivt skydd mot flodet av menstruationsvatska. Tampongen enligt uppfinningen är av starkt hoppressat slag och expanderar kraftigt i diametral riktning, da den fuktas med menstruationsvatska, till en storlek som är avsevart mycket storre an den ursprungliga. Tampongen enligt uppfinningen framgar av efterfoljande patentansprak. The present invention relates to a tampon which expands considerably after insertion into the vagina to provide a more effective protection against the flow of menstrual fluid. The tampon according to the invention is of a strongly compressed type and expands sharply in the diametrical direction, as it is moistened with menstrual fluid, to a size which is considerably larger than the original. The tampon according to the invention appears from subsequent patent claims.

Uppfinningen beskrives narmare i det foljande under hanvisning till bifogade ritning. 2201 2 Ddr visar fig. 1 en perspektivvy av en utforingsform av en tampong i enlighet med liggande uppfinning, innesluten i en vanlig anordning for inforing av tampongen i vagina. Fig. 2 ar en vy av baclrenomradet i kvinnokroppen i ett plan genom arvix och vaginaloppningen och visar en tampong enligt 18- religgande uppfinning i lage omedelbart efter inforandet i vagina. Fig. 3 är en vy liknande fig. 2 och visar, hur tampongen expanderar, dâ den fuktas med menstruationsvatska. Fig. 4 visar i storre skala en sektion efter linjen 4-1 i fig. 3. Fig. 5 är en perspektivvy av tampongens bestandsdelar i deras relativa lagen, innan tampongen formas, och fig. 6 är en perspektivvy, delvis' i sektion, av tampongens bestandsdelar enligt fig. 5, vikta pa mitten av deras langd och ihopknutna med ett utdragningssnore, innan de pressas till langstrackt, eylindrisk form for bildning av tampongen. The invention is described in more detail in the following with reference to the accompanying drawing. Fig. 1 shows a perspective view of an embodiment of a tampon in accordance with the present invention, enclosed in a conventional device for inserting the tampon into the vagina. Fig. 2 is a view of the bacillus area of the female body in a plane through the arvix and the vaginal opening and shows a tampon according to the 18-invention according to the invention immediately after insertion into the vagina. Fig. 3 is a view similar to Fig. 2 and shows how the tampon expands when moistened with menstrual fluid. Fig. 4 shows on a larger scale a section along the line 4-1 in Fig. 3. Fig. 5 is a perspective view of the components of the tampon in their relative layers, before the tampon is formed, and Fig. 6 is a perspective view, partly in section, of the components of the tampon according to Fig. 5, folded in the middle of their length and tied together with a pull-out cord, before they are pressed into an elongate, cylindrical shape to form the tampon.

Pa ritningen visas en tampong 1 i form av en langstrackt cylinder, innehallande absorberande material, sasom absorberande born-nil, rayon, pappers- eller tramassa, som är formad genom hoppressning av ett eller flera lager eller ark av sadant material till onskad form. Tampongen kan inforas i vagina me-deist en inforingsanordning 2, som bestar av ett yttre ror 3 och ett inre ror 1, anordnade teleskopiskt med det inre roret rorligt i det yttre roret. Tampongen passar exakt i den ena anden pa det yttre roret och kan skjutas ur detta, genom att innerroret f8res i langdriktningen i ytterroret i riktning mot tampongen. Ett utdragningssnore 5 är ldmpligen fastsatt i ena linden av tampongen for underlattande av dess avlagsnande efter anvandning. Snorets andar gã genom och utanfiir innerroret, sa att de aro tillgangliga. The drawing shows a tampon 1 in the form of an elongate cylinder, containing absorbent material, such as absorbent boron, rayon, paper or pulp, which is formed by compressing one or more layers or sheets of such material into the desired shape. The tampon can be inserted into the vagina by means of an insertion device 2, which consists of an outer tube 3 and an inner tube 1, arranged telescopically with the inner tube movable in the outer tube. The tampon fits exactly in one end of the outer tube and can be pushed out of this, by moving the inner tube in the longitudinal direction of the outer tube in the direction of the tampon. A pull-out cord 5 is typically attached to one of the wraps of the tampon to facilitate its removal after use. The spirits of the cord go through and outside the inner tube, so that they are accessible.

Da en langstrackt, cylindrisk tampong av konventionell form och storlek infores i vagina 6, intar den i allmanhet det lage, som visas i fig. 2. Tampongen utfyller icke vagina pa grund av vaginas form av ett platt-tryckt ror och pa grund av skillnaden i storlek mellan tampong och vagina. Tampongen kan ligga intill en sidovagg 7 eller i mitten pa vagina sasom visas pa ritningen, varigenom den lamnar en oppen vag, langs vilken vaginalvatska kan stromma fran cervix 8 ut genom vaginaoppningen 9. When an elongated cylindrical tampon of conventional shape and size is inserted into the vagina 6, it generally assumes the layer shown in Fig. 2. The tampon does not fill the vagina due to the shape of the vagina of a flat-pressed tube and due to the difference in size between tampon and vagina. The tampon can lie next to a side cradle 7 or in the middle of the vagina as shown in the drawing, thereby leaving an open cradle, along which vaginal fluid can flow from the cervix 8 out through the vaginal opening 9.

Enligt uppfinningen kan man erhalla ett bathe hinder mot stromning av menstruationsvatska medelst en tampong, som vid fuktning speciellt expanderar i en mer eller mind-re diametral riktning till en storlek, som hr avsevart storre an den ursprungliga, och vii-ken star i kontakt med en storre del av vaginavaggarna an tidigare tamponger. Ph grund av den genom expansionen okade volymen erhailer en sadan tampong en storre absorberande yta, sit att dess effektiva absorptions-f ormaga Ras. According to the invention, a bath can be obtained against the flow of menstrual fluid by means of a tampon, which on wetting especially expands in a more or less diametrical direction to a size which is considerably larger than the original, and which is in contact with a larger part of the vaginal cradles than previous tampons. Due to the volume increased by the expansion, such a tampon has a larger absorbent surface, due to its effective absorption-forming Ras.

En tampong med dessa fordelar framstalles av ett flertal lager absorberande material, anordnade som ett laminat i tampongens langdriktning. De intill varandra liggande lagren av absorberande material sta i intim kontakt langs en del av deras ytor och aro till en viss grad fasta vid varandra som en fOljd av det tryck, som anvants vid framstallningen av tampongen. Lagren aro emellertid icke fixerade i lage och atminstone delar ddrav kunna foras frail varandra. A tampon with these advantages is made of a plurality of layers of absorbent material, arranged as a laminate in the longitudinal direction of the tampon. The adjacent layers of absorbent material are in intimate contact along a portion of their surfaces and are to some extent attached to each other as a result of the pressure used in the manufacture of the tampon. However, the bearings are not fixed in position and at least parts of the drive can be moved apart.

De absorberande lagren dro sa anordnade, att de kunna foras fran sina ursprungliga lagen f8r okning av tampongens storlek, sit att en star-re del av vaginalvaggarna beroras, varigenom ett mera effektivt hinder mot vatskeflodet fran cervix mot vaginaoppningen bildas. En sadan rorelse hos lagren erhalles, genom att man i tampongen anvander ett starkt hoppressat, absorberande material, som expanderar tillrackligt vid fuktning, sit att lagren av absorberande material trangas utat bort fran varandra och mot vaginas vaggar. The absorbent layers are arranged so that they can be moved from their original layers to increase the size of the tampon, so that a larger part of the vaginal walls is due, thereby forming a more effective barrier to the fluid flow from the cervix to the vaginal opening. Such a movement of the layers is obtained by using a strongly compressed, absorbent material in the tampon, which expands sufficiently upon wetting, so that the layers of absorbent material are pushed outwards from each other and towards the cradles of the vagina.

Enligt en utfOringsform av uppfinningen kan man framstalla en tampong med en ungefarlig diameter pa 12 mm och en langd pa 45 mm genom formning av ett laminat av det slag som visas i fig. 5, som bestar av ett ovre lager 10 och ett undre lager 11 av absorberande bomull, vardera ungefdr 100 mm langt och omkring 25 mm brett. Det undre lagret 11, sour blir det yttre lagret i den fardiga tampongen, hr lampligen lattare an det byre lagret 10, for att den aterhallande effekt, som det yttre lagret kan ha ph expansionen av det svallbara materialet i tampongens inre, skall bli sa liten som mojligt. Det undre lagret kan exempelvis vaga omkring 1/2 gram och det ovre lagret omkring 1 1/2 gram. En inre remsa av kraftigt hoppressad, regenererad cellulosasvamp 12, som är ungefdr 65 mm lang, 5 mm bred och 3 mrn tjock och svallbar till en tjocklek pa omkring 16 mm vid fuktning med menstruationsvatska anordnas centralt i langdriktningen mellan lagren av absorberande material. I den fardiga tampongen kan en total expansion efter fuktning pa omkring 32 ram erhallas i det visade exemplet, dit svampen hr dubbelvikt. Svampen hr anordnad sit, att den kommer att expandera mot de ndrliggande absorberande lagren. Andarna 13 ph svampen aro lampligen belagna innanfor andarna 14 pa de absorberande lagren, som nor-malt dro mjukare, sit att svamPens andar tdckas med absorberande lager i den fardiga tampongen. 201 2 Det pa detta satt formade laminatet kan bindas ihop vid mittpunkten pa langden, sit att det tjockare Ovre lagret 10 bildar inre lager 15 i den fardiga tampongen och det tun-flare, undre lagret 11 bildar yttre lager 16. Lagren stracka sig i tampongens langdriktning med remsan av cellulosasvamp 12 mellan de inre och yttre lagren I samma riktning Del vikta laminatet placeras darpa i ett langstrackt cylindriskt verktyg med de Onskade dimensionerna och sammanpressas till den avsedda formen. Vid uttagandet ur formen kan det anbringas i en inforingsanordning av det slag som visas i fig. 1. According to an embodiment of the invention, a tampon having an approximate diameter of 12 mm and a length of 45 mm can be produced by forming a laminate of the type shown in Fig. 5, which consists of an upper layer 10 and a lower layer 11. of absorbent cotton, each about 100 mm long and about 25 mm wide. The lower layer 11, sour becomes the outer layer of the finished tampon, here slightly lighter than the outer layer 10, so that the restraining effect which the outer layer can have on the expansion of the swellable material in the interior of the tampon is so small as possible. The lower layer can, for example, weigh about 1/2 gram and the upper layer about 1 1/2 grams. An inner strip of highly compressed, regenerated cellulose sponge 12, which is approximately 65 mm long, 5 mm wide and 3 m thick and swellable to a thickness of about 16 mm when moistened with menstrual fluid, is arranged centrally in the longitudinal direction between the layers of absorbent material. In the finished tampon, a total expansion after wetting of about 32 frames can be obtained in the example shown, where the sponge has double weight. The sponge is arranged so that it will expand towards the adjacent absorbent layers. The spirits 13 ph the sponge are suitably coated inside the spirits 14 on the absorbent layers, which normally draw softer, so that the spirits of the sponge are covered with absorbent layers in the finished tampon. The laminate formed in this way can be bonded together at the midpoint of the length, so that the thicker upper layer 10 forms an inner layer 15 in the finished tampon and the thinner layer, the lower layer 11 forms an outer layer 16. The layers extend in the tampon longitudinal direction with the strip of cellulose sponge 12 between the inner and outer layers In the same direction Part folded laminate is placed darpa in an elongated cylindrical tool with the desired dimensions and compressed to the intended shape. When removed from the mold, it can be placed in an insertion device of the type shown in Fig. 1.

Vid inforandet i vagina medelst inforingsanordningen intar tampongen det i fig. 2 visade laget och bibehaller i huvudsak den ursprungliga formen och storleken. Da vaginalvatska fuktar tampongen, expanderar svampen 12 i riktning mot lagren av absorberande material pit bada sidorna darom, sasom visas i fig. 3 och 1, sa att det yttre lagret 16 tvingas utat i en riktning bort ifran tampongens langdaxel och mot vaginalvaggarna. De inre lagren röra sig icke mycket, da de aro i intim kontakt med varandra. Den ande av tampongen, dar utdragningssnoret 5 är fast, kommer icke att expandera mycket, da dess rörelse forhindras av snoret. Vid den visade utforingsformen kommer ej heller tampongens motsatta ande att expandera mycket, da svampen ar belagen innanfor tampongens an-de. Andarna pa lagren av absorberande material, som straeka sig utanfor svampens andar, aro i viss man haste vid varandra och forhindra darigenom tampongens expansion. Man kan emellertid eventuellt forlanga svampen till tampongens ande for att erhalla expansion vid delta stalle. Upon insertion into the vagina by means of the insertion device, the tampon assumes the layer shown in Fig. 2 and essentially retains its original shape and size. As vaginal fluid moistens the tampon, the sponge 12 expands toward the layers of absorbent material pit both sides thereof, as shown in Figures 3 and 1, so that the outer layer 16 is forced outward in a direction away from the long axis of the tampon and toward the vaginal walls. The inner layers do not move much, as they are in intimate contact with each other. The spirit of the tampon, where the pull-out string 5 is fixed, will not expand much, as its movement is prevented by the string. In the embodiment shown, the opposite spirit of the tampon will not expand much either, as the sponge is coated inside the spirit of the tampon. The spirits on the layers of absorbent material, which extend beyond the spirits of the sponge, are in some ways in a hurry with each other and thereby prevent the expansion of the tampon. However, it is possible to extend the sponge to the spirit of the tampon in order to obtain expansion at the delta stall.

Nar tampongen Or helt uppsvalld erhaller den en oval form efter langdaxeln med den storsta dimensionen i vaginas langdriktning. When the tampon Or is completely inflated, it acquires an oval shape along the long axis with the largest dimension in the longitudinal direction of the vagina.

I uppsvallt tillstand har tampongen en avsevart okad storlek och bildar fOljaktligen ett mera effektivt skydd mot flytningar av menstruationsvatska. Den kan latt avlagsnas efter anvandningen pit grund av sin kurviga form. In a swollen state, the tampon has a considerably increased size and consequently forms a more effective protection against discharge of menstrual fluid. It can be easily removed after use pit due to its curvy shape.

Den ovan beskrivna tampongen expanderar huvudsakligen utat i diametral riktning. Tampongen bOr darfOr lampligen inforas sit i vagina, att den expanderar i riktningen av det plan, som begransas av den platt-tryckta r8rform, som vagina intager. Om emellertid tampongen icke infores pa delta salt, kommer den i alla fall att verka tillfredsstallande, chit tampongen efter expansionen tenderar att rOra sig sit, att den installer sig sjalv i linje med det angivna planet. Dessutom kommer planet liven att forandras nagot och tendera att in taga en stallning i linje med formen pa den uppsvallda tampongen. Om det ar onskvart att framstalla en tampong enligt fOreliggande uppfinning, som expanderar i mer On tva riktningar, kan man begagna sig av lampliga utforingsformer av uppfinningen. En tampong, som expanderar i huvudsak i tva diametrala riktningar, kan exempelvis erhallas genom formning av tva satser laminara konstruktioner, liknande den i fig. 5 visade och som ligga ovanpa varandra, sit att de bilda ett kors, varpit varje sets vikes som visas i fig. 6, varpa de pressas till en tampong. Vid en annan utforingsform kan bredden pa svampen eller motsvarande material garas storre an i ovan angivna exempel och kan aven eventuellt ges samma utstrackning som de inre och yttre lagren. Vid denna utforingsform kommer tampongens huvudexpansion fortfarande att ske i diametral riktning, men en avsevard expansion kommer att aga rum i andra riktningar. Del ar darfor tydligt, att vid framstallning av tamponger i enlighet med foreliggande uppfinning, tampongdimensioner, mangden anvant material, sammanpressningsgraden vid formningen av tampongen och andra faktorer och konstruktionsdetaljer, avseende tampongdimensioner och tampongtillverkning, kunna varieras Mom vida omraden utan att man darfor gar utanfor uppfinningens ram. The tampon described above expands substantially outward in the diametrical direction. The tampon should therefore be inserted into the vagina so that it expands in the direction of the plane bounded by the flattened tube shape which the vagina assumes. However, if the tampon is not inserted on delta salt, it will in any case appear satisfactory, since the tampon after expansion tends to move so that it installs itself in line with the indicated plane. In addition, the plane life will change slightly and tend to take a position in line with the shape of the inflated tampon. If it is necessary to produce a tampon according to the present invention, which expands in more than two directions, suitable embodiments of the invention may be used. A tampon which expands substantially in two diametrical directions can be obtained, for example, by forming two sets of laminar structures, similar to that shown in Fig. 5, which lie on top of each other, forming a cross, folded each set folded as shown in Fig. 6, warp they are pressed into a tampon. In another embodiment, the width of the sponge or corresponding material may be greater than in the examples given above and may also possibly be given the same extent as the inner and outer layers. In this embodiment, the main expansion of the tampon will still take place in the diametrical direction, but a considerable expansion will take place in other directions. It is therefore clear that in the manufacture of tampons in accordance with the present invention, tampon dimensions, the amount of material used, the degree of compression in the formation of the tampon and other factors and design details, regarding tampon dimensions and tampon manufacture, can be varied widely without departing from the invention. frame.
